Macro assert_gt

macro_rules! assert_gt {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($arg:tt)+) => { ... };
}

Asserts that the first expression is greater than the second.

Requires that both expressions be comparable with >.

Uses

Assertions are always checked in both debug and release builds, and cannot be disabled. See debug_assert_gt! for assertions that are not enabled in release builds by default.

Custom messages

This macro has a second form, where a custom panic message can be provided with or without arguments for formatting. See std::fmt for syntax for this form.

Examples

assert_gt!(2, 1);

// With a custom message
assert_gt!(2, 1, "Expecting that {} is greater or equal than {}", 2, 1);

assert_gt!(5, 5);  // Will panic

// With a custom message
assert_gt!(5, 6, "Not expecting {} to be greater than {}", 5, 6);
